Abstract

A porous composite of LiFePO ₄/nitrogen-doped carbon nanotubes (N-CNTs) with hierarchical structure was prepared by a sol-gel method without templates or surfactants. Highly conductive and uniformly dispersed N-CNTs incorporated into three dimensional interlaced porous LiFePO ₄ can facilitate the electronic and lithium ion diffusion rate. The LiFePO ₄/N-CNTs composites deliver a reversible discharge capacity of 138 mA h g ^-1 at a current density of 17 mA g ^-1 while the LiFePO ₄/CNTs composites only deliver 113 mA h g ^-1, demonstrating N-CNTs modified composites can act as a promising cathode for high-performance lithium-ion batteries.
